A Medicare Supplement plan, also known as Medigap, is private health insurance designed to "fill the gaps" in Original Medicare (Part A and Part B). While Original Medicare covers many healthcare costs, it leaves you responsible for deductibles, coinsurance, and copayments. Medicare Supplement in Arizona helps cover these remaining out-of-pocket expenses, providing you with more predictable monthly healthcare spending.
The biggest difference is flexibility. With a Medicare Supplement plan, you can see any doctor or specialist in the United States who accepts Medicare—no networks or referrals required. Unlike Medicare Advantage, which often has $0 premiums but higher co-pays, Medigap plans have a monthly premium but cover most (or all) of your medical cost-sharing. In Arizona, seniors often choose Medigap if they travel frequently or want total control over their provider choice.
The most common choices for Arizona residents are:
The best time is during your Medigap Open Enrollment Period. This is a one-time, six-month window that begins the month you are 65 or older AND enrolled in Medicare Part B. During this period, insurance companies in Arizona cannot use "medical underwriting," meaning they must accept you regardless of pre-existing conditions and cannot charge you more for health issues.
If you apply outside of your initial six-month Open Enrollment Period or a "Guaranteed Issue" situation, Arizona insurance companies can use medical underwriting. This means they can review your health history and may deny coverage or charge higher premiums based on your health. This is why we recommend securing your Medicare Supplement in Arizona as soon as you are eligible.
Standardized Medicare Supplement plans do not include coverage for prescription drugs (Part D), routine dental, vision, or hearing aids. To get full coverage, most Arizona seniors pair their Medigap plan with a standalone Part D Prescription Drug Plan. At Smile Insurance Group, we can help you bundle these separate policies to ensure you have no gaps in your care.
